Can I stir things up?
The timing kits seem to be £170+. Not sure what else I need to change with it. So pity to change it if the one on there is good (and better than buying a cheap kit)
With 48k being the time to change timing belts that means it probably will have been done once already. So 48 x 2 = 96k miles less 85k miles on clock 11k miles to go.
I will do a check on whether the belt has hardened or been marked. If a car is parked up the belt goes hard. But this engines seems to have done low miles at low revs all along.
Using this method with an ecotec X20XEV 16v vauxhall which was supposed to be changed every 4 years or 40k miles for the timing belt (or at 25k for a hard revving boy racer), i bought a car on around 45k drove to around 85k over a ten/eleven year period, and took the belt kit off to do the HG, and when I changed the water pump which on those engines is usually the problem, but never renewed any of the belt kit (two pulleys a tensioner and belt) in ten/eleven years. And it looked very healthy after ten/eleven years.
I understand Vauxhall and Rover and similar car makers aimed for around 80k miles before changing the kit but failures in various driving conditions meant they "play safe" and half that to around 40k. With Vauxhall's if the kit does not go hard and brittle or tensioner go slack, or by bad luck the belt fray then the water pump is usually the problem. (But I changed the pump as it trickle leaked). Boy racers rev the engine much more so that shortens the life of the belt kit so they say change every 25k for boy racer driving.
But by driving low miles regularly at low revs and most important without hard sudden acceleration and carefully inspecting the kit, they can last much longer...... even the ten/eleven years with one of my previous cars.
I was very impressed with the photos I would take of the condition of the belt kit after 11 years. Very clean and in good condition like new. Gave me a smile.
